WILLIAM S. G. BAKER, OF BALTIMORE, MARYLAND.

CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 276,210, dated April24, 1883. Application filed February 27, 1883. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM S. G. BAKER, of Baltimore, in the county ofBaltimore and State of Maryland, have invented certain new and usefulImprovements in Oar-Axle Boxes, of which the following is aspecification, reference being had to the accompanying drawings, inwhich I Figure 1 is an end elevation of an axle-box and adjacent partsas if in position under a car. Fig. 2 is a vertical section on the line2 2 of Fig. 1. Fig. 3 is a side elevation of the box, showing onecar-spring in elevation, and Fig. 4 is a view showing on the right aface view of one-half of an annular, flanged, and recessed metallicaxle-plate, and on the left a face view of one-half of an annularprojection of the carwheel.

Referring to the letters on the drawings, A indicates an axle; B, awheel; 0, an axle-box;

D, a brass bearing; E, a suspension-link; F, a

grooved iron shoe or washer supported by the link, and upon which thespring-carriage Gr rests; H, car-springs; I, spring-bolts, and K a beammaking part of a car-frame to which the spring-bolts are secured. All ofthese parts, so far as described, are of ordinary construction, and areonly referred to by way'of pointing out what is old, the better todistinguish what I deem to be now, which I will now describe.

First. Heretofore the spring-bolts I, which depend from the beam K inconnection with this class of boxes and have to sustain the strain ofthe swaying of the car-body,have been inadequately braced, and it hasbeen found desirable to strengthen them by an improved means of bracing.Accordingly I have designed a peculiar bracket-brace, L, provided with acentral aperture, so that it will slip over the outer end of theaxle-box, and also provided with bent arms M, extending under thesprings, and having holes to receive the lower ends of the spring-bolts.This brace is secured to the outside of the beam K by boltsor screws inany suitable way, and serves to stay the lower ends of the spring-bolts,while it accommodates the axle-box and gives a better finish to the car.I prefer to make it, as illustrated, in one piece; but it could be madein two parts;

I or two independent braces, one on each side of the box, reaching tothe lower end of each spring-bolt, might be employed without deing atthetop, through which the forked key cess in the end of the axle. Thisopening I cover by a cap, P, resting or fulcrumed at its inner end bymeans of the bent end or lug X on the top of the box, as wellillustrated in Fig. 2, and held in place by the bolt or bolts Q, whichserve, when screwed home, to bring the outer end of the cap down uponthe top of oil-tight joint. The brass bearin g D isinserted from theback end of the box.

the outer vertical wall of the box and make an Second. I provide the box0 with an open- Third. I provide an annular plate, R, to encircle theaxle between the box, and an annular projection, S, upon the car-wheel.This plate is provided with recesses, as indicated in Fig. 4, and, say,for example, eight in number,-more or less. The annular projection uponthe wheel is provided with pins or lugs S- say four in number-to-fitinto alternate recesses in the plate. The remaining recesses in theplate contain suitable coil-springs, T, bearin g upon the bottoms oftheir recesses in the plate at one end, and upon the face of the annular projection S at the other end. This plate is provided withsegmental flanges U, and between it and the box is a suitable annularleather washer, V.

From this description of the structure and the springs will tend tobrace the plate against the leather washer and the washer against theinner end of the box. The pins within the recesses will serve to turnthe plate, and with it parting from the substance of my improvej O canbe put in place to fit in the annular re- I arrangement of the parts itwill be seen that 5 the washer. The metal plate and washer turnroo ingwith the axle are made to fit tightly upon I 3. In combination with theaxle-box and it. The result of this structure is to produce an oil anddust tight joint affording thorough protection to the journal of thecar-axle and the brass bearing within the box.

Having thus described my improvements, what I claim, and desire tosecure by Letters Patent of the United States, is-

1. The combination, with the beam K and the spring bolt or bolts I, of'abrace, L, rigidly secured to the beam and extending down past theaxle-box, and rigidly secured to the lower end of one or more of thespring-bolts, substantially as and for the purpose set forth.

2. The axle-box provided with the opening at-the top, in combinationwith the cap P, fulcrumed'at its inner end by means of the lug X on topof the box, and screw-bolts Q, for bringing the outer end of the capdown upon the wall of the box to form a tight joint, substantially asset forth.

wheel, the annular plate R and Washer V, constructed and arranged torevolve with the wheel, substantially as and for the purpose set forth.

4. The combination of the wheel provided with the annular projection Sand pins S, the annular recessed plate R, carrying the springs T, thewasher V, and axle-box G, constructed 30 and arranged substantially asand for the purpose set forth.

In testimony whereof I have hereunto subsgribed my name this 19th day ofFebruary, A.
